Gaim is an instant messenger client that can handle multiple protocols.
Stefan Esser audited the Gaim source code and found a number of bugs that have security implications. Many of these bugs do not affect the version of Gaim distributed with version 2.1 of Red Hat Enterprise Linux.
A buffer overflow exists in the HTTP Proxy connect code. If Gaim is configured to use an HTTP proxy for connecting to a server, a malicious HTTP proxy could run arbitrary code as the user running Gaim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0006 to this issue.
An integer overflow in Gaim 0.74 and earlier, when allocating memory for a directIM packet for AIM/Oscar, results in heap overflow. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0008 to this issue.
Users of Gaim should upgrade to these erratum packages, which contain a backported security patch correcting this issue.
Red Hat would like to thank Steffan Esser for finding and reporting these issues and Jacques A. Vidrine for providing initial patches.
